What Is A2O Entertainment, and What Does A2O Mean?

Most K-pop agencies are named after a person, a place or a slogan. A2O is named after an alphabet. The letters stand for "Alpha to Omega," the first and last letters of the Greek alphabet, and the company's own overview describes a journey that fans and artists share from its beginning (Alpha) to its end (Omega). At the October debut show, Lee Soo-man put it more simply: a beginning and an end that connect and then start again. You read the name as "A-two-O," and the middle character is the letter O, not a zero. "A20" is one of the most common misspellings online, and it leads to the same company.

The man behind it is the reason most people search for it. Lee Soo-man founded SM Entertainment in 1995 and launched groups such as BoA, TVXQ, Girls' Generation, SHINee, EXO and aespa. He left SM in 2023. When he sold his SM shares, he agreed not to produce music in Korea for three years, and that restriction ended in February 2026. A2O Entertainment, headquartered in Singapore, is what he built in the meantime. It launched its first group, aimed at China and the United States, in 2024, and it now also runs a Korean office, A2O Entertainment Korea, in Gangnam, Seoul. At A2O his official credit is key producer, and the label's videos sign him as "S.M. LEE."

The company describes its mission in three parts: A2O ROOKIES, a system for training new artists; Celebrity IP, original characters and stories built around its idols; and Play2Create, a plan to let fans remix and build on that material. Everything is filed under one label for its music, "Zalpha Pop," a name made from Generation Z and Generation Alpha, the listeners it is written for.

A2O MAY, A2O SOUL and A2O LITE at a Glance

A2O now has three groups, and their names look so alike that they are easy to mix up. Here is the short version:

• A2O MAY: the label's first group, a five-member girl group made up of Chenyu, Shijie, Quchang, Miche and Kat. It debuted on December 20, 2024, with "Under My Skin," and has worked mainly in China and the United States. Three members are Chinese and two are American, and Miche and Kat are twins. Its newest song, "BAD HABITS TONITE," came out on October 18, 2026.
• A2O SOUL: a 15-member boy group with members from Korea, Japan, China, Thailand and the United States. It debuted in Korea on October 13, 2026, with "Superstar," a synth-pop single the label calls "new synthwave."
• A2O LITE: a nine-member girl group with members from five countries. It debuted the same day with the digital single "NEON," a bass-heavy dance track.

So when someone asks for "Lee Soo-man's Chinese girl group," the answer is usually A2O MAY. When they ask about his new K-pop girl group, they mean A2O LITE. SOUL and LITE share a debut date, a producer and a story; MAY came first and stands slightly apart, though it shares the Zalpha Pop label and the same producer credit. The official site explains MAY's name as five girls "blossoming like May flowers."

This guide stays with the big picture. For names, nationalities and first stages, see our guides to the A2O SOUL members and the A2O LITE members.

The ACE Universe and the Planet Soulite

Why does a K-pop label need a planet? Because Lee Soo-man has always liked his groups to arrive with a world attached, and A2O's world is called ACE, short for A2O Cosmic Epic. It is set on Soulite, a planet where anything you wish for can be made, and where something is still missing.

That missing piece shapes both new groups. In the official story, the boys of A2O SOUL leave Soulite for Earth to find their own "soul," which the label defines as the emotion and energy that make a person feel alive: happiness and love, excitement and passion. On Earth they meet other boys, discover what was empty in themselves and change one another along the way. A2O LITE are told through color instead. Each girl's color begins with a moment that shaped her, the first thing she liked or loved, and when the colors meet they make a new light. The label also says members can form new units or work solo across team lines, so the story is built to grow.

On October 27, 2026, the label's A2O WORLD channel released a trailer for the universe itself, "A2O COSMIC EPIC: Welcome to SOULITE." Its opening narration goes back to a time long ago on Earth, then describes life on Soulite: a technology called PICO that understands the world down to the atom and can make whatever is needed, even new eyes or a new heart, so that people there live far longer than we do, though not forever. Then the tone turns. Lately, the narrator says, beautiful things no longer move them, and good news no longer makes them happy. It sets up exactly the emptiness the two groups go looking to fill. The description lists the credits as "Zalpha Pop by A2O, Produced by S.M. LEE, Powered by CAWMAN." When A2O first introduced itself in 2024, it explained CAWMAN as shorthand for the kinds of content it planned to make: cartoon, animation, webtoon, motion picture, avatar and novel.

L, S, M: The Fan Theory in the Group Names

Here is the detail fans enjoy most. Line up the three group names, LITE, SOUL and MAY, and read only the first letters: L, S, M. Those are the initials of Lee Soo-man, the producer behind all three. It is a reading that circulates among fans, and it is easy to see why it sticks: the label's own credits sign him as "S.M. LEE," and every group name follows the same pattern, A2O plus one short word.

Is it on purpose? Nobody outside the company can say. A2O Entertainment has not publicly addressed the reading, and its official descriptions explain each name on its own terms: MAY for girls blossoming like May flowers, SOUL for the feeling the boys travel to Earth to find, and LITE for different colors coming together as a new light. So treat L-S-M as a fan theory, a neat coincidence fans spotted, not a confirmed fact. If the label ever adds a fourth group, you can be sure fans will check its first letter before they hear a note.

The puzzle also says something about how K-pop fandom works. Names, colors and numbers are read as clues long before a song comes out, and a label that builds a whole planet around its groups is inviting that kind of reading.

The People and the Technology Behind the Debut

Two names come up in almost every conversation about A2O's sound. The first is Yoo Young-jin, the longtime SM producer behind hits for TVXQ, SHINee, Girls' Generation and aespa, who worked on the music and performances of both new groups and gave each one a different color. The second is Sunny of Girls' Generation, Lee Soo-man's niece, who signed an exclusive contract with A2O in April 2025. She joined as a producer rather than a performer: she trained in production under Yoo Young-jin and has worked on the trainees' education program, choreography and styling. You will not see her on stage with the groups, but fans who search "A2O Entertainment Sunny" are looking for exactly this role.

The technology came second at the debut show, but it was hard to miss. Lee presented 4DGS, short for four-dimensional Gaussian splatting. Many cameras record a performance at the same time from different angles, and the footage is rebuilt as three-dimensional data that moves through time, so a viewer can watch from almost any position. The label developed it with the U.S. company 4DV Intelligence and worked with Samsung Electronics to optimize it for XR headsets, and an XR zone at the debut show let guests try it. Lee described the idea as moving from a camera that records to a camera that creates, and both debut music videos were shot this way.

If that sounds familiar, it should. More than a decade ago, Lee built the Matrix camera rig that froze members of BoA, TVXQ, Girls' Generation and SHINee in mid-air while the camera circled them. 4DGS is the same instinct with video instead of still photographs.

Charts, the Next Release and the A2O Zalpha Audition

The first two weeks went well. "NEON" reached No. 1 on Melon's Top 100 about 29 hours after release, and A2O LITE then won four music show trophies in six days without a physical album: SBS Life's The Show on October 20, MBC M's Show Champion on October 21, Mnet's M Countdown on October 22 and SBS Inkigayo on October 25, their first win on a terrestrial network. Our story on A2O LITE's first win with "NEON" covers how it started. A2O SOUL is next. Its first EP, also titled "Superstar," is scheduled for November 9 at 6 p.m. Korea time, with five songs and a second title track, "Dancing in the Dark." Our guide to the A2O SOUL "Superstar" EP has the details.

If you would rather join than watch, the label runs an open audition in Seoul. According to the official website, the A2O Zalpha Audition takes place every Sunday from 1 p.m. to 4 p.m. Korea time at A2O Entertainment Korea in Gangnam. There are four categories, vocal, dance, acting and modeling, and you choose one. It is open to everyone regardless of age, nationality or gender. You register on site on the day, and only individual applications are accepted.

A few house rules are worth knowing before you go. Vocal auditions are sung a cappella, and dance music is played at random, so there is nothing to prepare. Applicants under 14 must bring a guardian's signed consent form, and there is no waiting room for guardians. Auditions pause over the Seollal and Chuseok holidays. Only selected applicants are contacted, within two weeks. The site also lists email, Instagram (@a2o.audition) and KakaoTalk or LINE (a2o.audition) as official channels.
